Description
Technical field
The utility model belongs to the rubber manufacturing machinery technical field, is specifically related to a kind of parallel grinding head rubber refined slimer in the reclaimed rubber machinery.
Background technology
The present parallel grinding head rubber refined slimer that uses, as shown in Figure 1, micelle adds in the feed hopper 31 (two shear, and the grinding working surface is the plane).Micelle is transported in the storing space of deciding bistrique 10 and moving bistrique 11 by feeding spiro rod 6, deciding bistrique 10 is fixed on and decides in the bistrique support 9 right-hand member seams, unclamp locking handwheel 23, clockwise rotate adjusting handle 29, regulate pinion 24 by reduction box 30, driving adjusting gear 22 rotates, adjusting gear 22 is by 26,2 7514 taper roll bearings of rear end cap, adjusting gear spacer 25, main shaft is moved to the left, make the gap smaller of deciding between bistrique and the moving bistrique, thereby the rubber powder that grinds is thinner relatively.Otherwise, rotating counterclockwise adjusting handle 29, main shaft 13 drives moving bistrique and moves right, and make the gap of deciding between bistrique and the moving bistrique become big, thereby the rubber powder that grinds is thicker relatively.
Prior art has following shortcoming and defect:
1, owing to moving bistrique rotates on the one hand, axially move again simultaneously, so drive the main shaft of moving bistrique rotation, except the supporting of spindle bearing holder 19 and 4 42221 bearings is housed, left sliding sleeve 15 and right sliding sleeve 20 also must be housed, otherwise main shaft just can't straight line moves and adjusts moving bistrique and decide gap between the bistrique; So just caused the radial clearance of main shaft that the movement clearance of 42221 bearings is not only arranged, the gap of sliding sleeve is also arranged simultaneously, and the gap of sliding sleeve generally has been more than 5 times of bearing clearance.So when the moving bistrique of main shaft drive rotates, because the radial motion gap is big, moving bistrique beat and produce bigger motion noise, and if desired rubber powder fineness thin more, then moving gap of deciding between the bistrique is just more little, and because the beat of moving bistrique must contact with deciding bistrique, therefore the ear-piercing noise that produces like this is bigger, and because the beat of moving bistrique makes it and the depth of parallelism of deciding between the bistrique is bad, therefore rubber powder can not be levigate, and coarse granule is more, and fine glue powder content is few.
2, feeding spiro rod 6 is stuck easily: because between screw rod 6 and the machine barrel 8 certain interval is arranged, when charging is difficult for the card machine during for particle, but when certain thin slice material is arranged in the material, thin slice will be stuck between screw rod external diameter and the machine barrel, form voussoir, make screw rod change motionless, the motor that drives screw rod is produced even is burnt out in influence.
3, equipment uses after the some months, and thin rubber powder will enter in the bearing 60212 and 8112 of spiro rod rear end, makes screw rod change motionless, and the easy burn-out motor must be dismantled again, cleans, install, and it is unfavorable to bring to production.
4, the rubber powder temperature is too high, influences rubber powder quality and sieving rate.Because the just moving bistrique of cooling segment and decide bistrique water flowing cooling, and rubber powder collection conduit, blower fan, gatherer all do not have water flowing to cool off, shown in prior art blast system figure.Though move bistrique and decide bistrique water flowing cooling, but the rubber powder temperature that grinds is still very high, and the long and hot rubber powder of transfer pipeline, blower fan and rubber powder gatherer contacts and does not force cooling medium, cause the rubber powder cooling not got off, rubber powder burns smolders and influences the rubber powder quality, also influence the sieving rate of rubber powder, even the security incident that happens occasionally and catch fire.
5, an idle work zone is arranged between all areas of feeding spiro rod 6 ends and the moving bistrique, this region area does not only play and makes rubber powder shear the effect of pulverizing, and consumes main motor current on the contrary, and increases the rubber caloric value, and is very unfavorable to machine performance.
6, the screw thread of feeding spiro rod 6 is an one start screw, and the one start screw feeding is inhomogeneous, and uneven feeding causes bistrique one rim charge many, and a rim charge is few, and is stressed suddenly big or suddenly small, causes main current of electric fluctuation range very big.Can cause 2 kinds of results like this: 1, output, fineness instability; 2, easily burn motor.
Summary of the invention
In order to overcome the shortcoming of prior art, it is a kind of that the utility model provides: moving bistrique does not move, deciding bistrique moves, machine barrel is with longitudinal fluting vertically, and feeding spiro rod is double end or multiple thread, and screw thread and tail bearing supporting part are provided with a plurality of grooves, bistrique shelves material cover, transfer pipeline, blower fan, the equal water flowing cooling of rubber powder gatherer, do not have relative motion between screw rod end and the moving bistrique, same main shaft, the moving same rotating speed of bistrique rotate simultaneously, do not produce the parallel grinding head rubber refined grinder with high performance of idle work.
As follows in order to realize the technical scheme that the utility model adopts: the main shaft right-hand member that drives moving bistrique rotation is adorned 2 roller bearings, one dottle pin is arranged between two roller bearings, the main shaft left side is adorned respectively a thrust bearing dottle pin between a thrust bearing and roller bearing, thrust bearing and the roller bearing, 2 sealing gasket, main shaft high order ends that prevent that lubricating oil runs off are arranged in the middle of the main shaft is big belt pulleys, and the power of motor drives main shaft and moving bistrique rotation by small belt pulley, belt.In order to make main shaft and to be installed in part easy installation and removal on the main shaft, the main shaft supporting seat adopts half slide structure (two parts divide equally from the axle center form) up and down; In order to solve main shaft diameter to the low shortcoming of running accuracy, between diametric(al), main shaft and the main shaft supporting seat of main shaft bearing, except bearing is arranged, do not have any parts such as sliding sleeve, and main shaft can only rotate, can not moving linearly.
Decide bistrique basal disc machine barrel endoporus and be processed with the mating part of feeding spiro rod screw thread vertically and help the groove that feeding is difficult for getting stuck, and the quantity of groove is greater than 2.Deciding bistrique basal disc machine barrel packs into and decides in the endoporus of bistrique support, the shape of deciding the bistrique support is that the left end diameter is little, the right-hand member diameter is big, right-hand member has the endoporus seam, and right-hand member diameter general goal has half through hole, the adjust the play nut is packed in the endoporus seam, and a thrust bearing respectively is equipped with on the both sides of adjust the play nut, adjust the play nut 25 by half through hole with regulate pinion 40 interlocks.The endoporus of adjust the play nut is a screw thread, and external diameter is a gear.Feeding spiro rod is packed into and is decided in the bistrique basal disc machine barrel, the front end of feeding spiro rod and moving bistrique is fastening combines as a whole, and with moving bistrique and main shaft, simultaneously, same rotating speed rotation (fastening can use bolt, screw thread, key and tapering connection fastening).Be illustrated as spiral marking connection.
Feeding spiro rod is double end or multiple thread, between screw thread and the tail bearing supporting position cylinder the same with the major diameter of thread size more than 2 is arranged, 2 middle grooves that have one section size to form of cylinder less than 2 cylinder dimensions, sliding sleeve 31 is equipped with in the rear end of feeding spiro rod, ball bearing 28 and bearing holder (housing, cover) 29, along the diametric(al) of ball bearing 28, the sliding sleeve of an interior hole dimension greater than the screw diameter size is housed between screw rod and the bearing holder (housing, cover).
Bistrique material retaining hood, wind send pipeline, blower fan, rubber powder gatherer all to adopt double-decker water flowing cooling.
Beneficial effect: only move axially and do not rotate owing to decide bistrique, move forward and backward behind the active gap of deciding between the bistrique of adjustment locked (with engine lathe tailstock functional similarity).And moving bistrique and main shaft link together with fastening bolt, because main shaft only rotates and does not move axially, thereby main shaft does not need to use sliding sleeve, so only there is the gap of bearing in main axis rotation, and has not had the gap of sliding sleeve, so its running accuracy has improved several times, moving bistrique is beat not, and the depth of parallelism of deciding between the bistrique is good, moving bistrique with decide bistrique and do not contact, so operating noise is low, the rubber powder that grinds is meticulousr.
According to helical feed principle and practical experience, machine barrel frictional force vertically is the smaller the better, be that axial fineness is bright and clean more, roughness is more little, material is easy more to be fed forward, and fineness radially is coarse more good more, like this, material just is not easy " embracing " screw rod, threadedly makes circular motion together and is not fed forward.So, machine barrel is processed with the groove more than 2 vertically, can increase machine barrel frictional force radially, prevent that material from " embracing " screw rod, the threaded rotation together and not moving forward, simultaneously, groove can prevent again that thin slice material and granule material are stuck between machine barrel and the feed worm rib and form the angle of wedge and stuck screw rod, not rotate.Because after fluted, the gap between groove and the screw rod external diameter is just big, and the thin slice material will enter in the groove and card screw rod incessantly.
Feeding spiro rod is double end or multiple thread (2 above helixes), can solve inhomogeneous and the problem that the main frame current unevenness that causes is even of one start screw feeding spiro rod, because the one start screw discharging is fixed on the direction of that helix all the time.Because the feeding of single-head screw is inhomogeneous, a rim charge is many less to making bistrique and decide bistrique one rim charge, and makes main current of electric fluctuation range very big, often overload and burn out main motor easily, and the rubber powder fineness that grinds is inhomogeneous.Because multiple thread (more than 2 statures) is to divide equally symmetrical discharging all the time, enter moving bistrique and along the circumferential direction divide equally with the material of deciding bistrique, so current value is motionless substantially, it is very little to fluctuate, the rubber powder fineness of producing is even.
Feeding spiro rod and moving bistrique connect the following benefit that fastened as one:
1, owing to do not have relative motion between screw rod end and the moving bistrique,, output is improved so solved the shortcoming that consumes main motor portion of energy (idle work) fully.
2, owing to do not have relative motion between screw rod end and the moving bistrique, just can not produce frictional heat, thus micelle just can not take place also to shear grind before just " preheating ".Thereby it is good to shear the rubber powder quality of grinding out, and sieves the sieving rate height easily.
3, since the end thread of feeding spiro rod part from the ball bearing support distance of positions of rear end from far away, several grooves are arranged again between screw thread and the ball-joint, groove has played labyrinth seal function, and the volume space of groove is bigger, even there is rubber powder to enter, that also can hold is following, can not enter in the ball bearing.
Bistrique material retaining hood, wind send pipeline, blower fan, rubber powder gatherer all adopt double-decker, the water flowing cooling, can cool down the rubber powder that comes out from bistrique fast and effectively, prevent that the rubber powder temperature is too high, influence the rubber powder quality, smolder even catch fire, and prevent the rubber powder adhesion, influence sieving rate, help improving the output of thin rubber powder.
